Features of HP Hub & Switch Management
■ Scalable solutions from 10 Mbps t o Gig ab it Et hernet
■ Blocks unwanted traffic with Protocol Filtering
HP Proactive Networking produc t s save time, money and increase productivity. The agent-enabled, web-based management component of Proactive
Networking is embedded in newly introduced HP managed hubs and switches.
It consists of a Java-based W eb agent and an embedded webserver.In the past,
if you wanted to see a graphical representation of your network or get devicespecific information, you had to first load management software on a specific
station and then be at that station to view the screens.
Y ou can now use most W eb browsers that supports Java and frames. There is
no need to learn a new application. Y ou see th e same interface wi th the same
look and feel —Java is operating-system independent. You can use a Web
browser on any networked computer, day or night, to configure, control, and
monitor networkingdevices (managedhubs andswitches), andto query faults
from any of these devices. You will immediately see the reduced cost of
ownership, since the devices can be managed with minimal effort anytime,
anywhere, and with any platform.
Using your Web browser, you can now perform network management functions for several HP devices.
Note: The device must have an IP address in order to be managed with
a browser. The management station must also have an IP address.

* The more OpenView Windows (ovw) sessions you run, the more OS configured swap
space will be necessary. A good guideline is to configure 25 megabytes of swap space for
each additional ovw session t hat you expect to run.
Required Network Configuration
The installation starts the automatic discovery and layout of the network
map, based on your internetwork’s IP addressing scheme. This depends on
the following:
■ Correct IP addressing. The IP addresses and subnet masks must be
correctly configur ed on the manager station, and on all rou t ers and
gatewayhosts that supportSNMP . Otherwise, the automaticallygenerated
map could contain incorrect networks with nodes from outsidethe administrative domain.
■ Network design that aids isolation of network faults and traffic, by doing
the following:
• Logically subdividing an internetwork into manag eable-sized
networks and subnetworks, using routers, gateway hosts and IP
subnet addressing.
• Physically subdividing networks and subnetworks into manageablesized segments using hubs, bridges, and gateway hosts. HP recommends that the segments have no more than 200 nodes each.
■ SNMP-based, MIB-I (RFC 1156) or MIB-II (RFC 1213) compliant agents
running on management stations, routers, and gateway hosts at a
minimum, and running on bridge s and hubs for manageable segments.
This ensures speed and accuracy of map generation.
■ All HP 9000 Systems (manager stations or hosts) that a re running HP-UX
version 10.20 or HP-UX ve rsion 11.00 should also be running the HP
OpenView SNMP Agent software as part of their ne tworking software.
■ All managed HP devices should contain a supported version of ag en t
firmware.

Before Installing HP Hub & Switch Management
Before you can begin installing HP Hub & Switch Management, you must
have successfully completed installing y our Network Node Manager
product. See the HP OpenView Network Node Manager Products
Installation Guide for instructions on installing the HP Network Node
Manager and obtaining your software license.
You may set up multiple manager sta ti ons on y our network. Each manager
on which you install the manager produc t set does its own p olling, so the
manager traffic on your network will increase in proportion to the number of
managers.
Note: This applies only if you buy multiple copies. Your license only
entitles you to instal l one copy.
If you are installing this product set on a workstation with an existing
application, be sure you first exit any ovw sessions currently running, then
stop all HP OpenView processes using the ovstop command (available to
root user).

Note: It is also a good practice to make a backup of your curr ent
OpenView application (especially your network map) before
proceeding with the installation of new applications.
Installation Directories
The HP Hub & Switch Management pr oduct is installed in the following
directories:
• /var/opt/HPASA
• /opt/HPASA
In compliance with the OSF standards, the /opt/HPASA directories hold the
read-only files, which include a ll th e executables, libraries, release notes,
and Device Model Files. The /var/opt/HPASA directories contain the
writeable directories such as product data directories. Be sure you have the
required amount of free disk space before you install the products. You can
make one of the following arra ngements for the required space:
• having the requi r ed amount of disk space in /opt and /var
• mounting a dedicated volume for /var/opt/HPASA and
/opt/HPASA
• making /var/opt/HPASA and /opt/HPASA symbolic links to a
file system with enough disk space.
The management system must have b oth manager and agent software
installed.
Make sure the drive that you will be loading from is connected to the
workstation and that your workstation is configured to recognize the CDROM drive.

HP Hub & Switch Management Overview
HP Hub & Switch Management for OV-UX is a network management
application that allows you to manage and control Hewlett-Packard (HP)
hubs, bridges, and switches on a TCP/IP network. HP Hub & Switch
Management runs on the HP OpenView pla t form, which allows multivendor
enterprise-wide network man age me nt. For communications with managed
devices, Hub & Switch Ma nagement uses the Simple Network Management
Protocol (SNMP)—an industry standar d ne twork management
communications protocol.

Introduction to HP Hub &
Switch Managemen t
HP Hub & Switch Management is integrated with HP OpenView Network
Node Manager applications.
When using Hub & Switch Manag e me nt, you can do the following:
■ use HP OpenView functions to automatically discover and display the IP
map (and submaps). HP hubs, bridges, and sw it ches that are set up for
SNMP/IP operation will be displayed as appropriate “connector” devices.
■ use your Web browser to launch Device Views for Proactive networ k
management
■ manage HP hub and switch security features
■ run network tests to troubleshoot network or device problems

HP OpenView Network Management Platform
HP OpenView Network Management
Platform
HP OpenView is a “platform” for network management applications. As a
platform, it allows multiple network management applications that are
OpenView compliant—such as HP Hub & Swit ch Management—to share
platform functionality and a common display.
Using the HP OpenView, Network Node Manager provides many shared
management functions, which include:
■ automatic discovery and mapping of IP networks and objects
■ dynamic submap creation
■ map navigation Tool Bar
■ Quick Navigator
■ a map zoom viewer
■ device polling to monitor de vices on an OpenView map
■ an event notification and logging system
■ generic SNMP device m a nagement
■ graphing and logging of traffic
■ client/server architecture enabling processes to be run on other worksta-
tions

Definitions, Processes, and Files
The basic concepts and processes of management for networks are
described briefly in the following paragraphs.

Introduction to HP Hub & Switch Management
Definitions, Processes, and Files
SNMP Manager and Agents
HP Hub & Switch Management uses SNMP (Simple Network Management
Protocol) to communicate with managed devices. SNMP commands are
transmitted and received on the network using the Internet Protocol (IP).
The network management station used to run Hub & Switch Manage ment is
referred to as an SNMP manager system. HP devices with SNMP agents ar e
called agent systems . Each network management operation requested by
the manager system is executed by one or more agent systems.
The manager system communicates with HP devices to retrieve or modify
management information. The devices contain Network Management SNMP
Agent software to support this communication.
Note: For Hub & Switch Management operation, you must set up HP
network devices for SNMP/IP operation. See
Appendix A for more
information.
Community Names for Manager and Agent Interaction
Most SNMP exchanges involve a community name, which can be thought
of as a password for a managed device or group of devices.
Depending on the device, SNMP get requests for information from a device
agent may require the manager to supply a community name that is
configured on the device.
Introduction to HP Hub &
Switch Managemen t
If a password has been specifically configured on a device, then password
authentication is required to perform any SNMP set operations that alter the
configuration or invoke self-test or reset on that device. The manager system
automatically asks you fo r t he password, then puts the encrypted password
in the community name field of subsequent set operations.
Configuring a password on HP devices is recommended but not required. As
described later in this manual, you can use Hub & Switch Management to set
a device password.

Running HP Hub & Switch Management
This chapter describes how to start and stop HP Hub & Switch Management.
It includes the following topics:
■ Starting the Manager Application
■ Verifying Installation of the Manager Product Set
■ Stopping and Restarting the Manager Application
Note: Before you begin, yo u should ensure that the network devices ar e
properly set up for IP operation. For information on setting up HP
network devices, see
Starting the Manager Application
Appendix A

The entire product set that you have installed is started as one application,
“the manager”, on your management stat ion. In other words, HP Hub &
Switch Management starts along w it h Ne twork Node Manager.
Starting HP OpenView
Do the following steps to start your product.
1. Add /opt/OV/bin to your path using one of the commands below. Note
that you only need to do this the first time you start the HP OpenView
manager software.
For These Shells Use These Commands
/bin/ksh or /bin/
sh
/bin/csh� setenv PATH “$PATH:/opt/OV/bin:/usr/
PATH=$PATH:/opt/OV/bin:/usr/sbin
export PATH
sbin”

2. Optionally, execute the /opt/OV/bin/ovstatus command to verify
that the trapd, ovwdb, ovtopmd , and netmo n background processes are
running. If the background processes are not running, execute the
/opt/OV/bin/ovstart command. If you are surprised that a background process is not running, run ovstart -v, whic h gi ve s you more
information. The ovstart command starts the background proc esses.
(You must be root to perform this step.)
3. If you are not running X Windows (X Windows, HP VUE or HP CDE for
HP-UX systems), start it.
4. Optionally, if you want to redirect your X Windows displa y to a system
other than the management system:
a. Set your X Windows
management system using one of the commands below. Replace
hostname with the host name of the sy stem to w hich you are
redirecting the display.
For these shells Use these commands
DISPLAY
variable onthe HP OpenView network
Running HP Hub & Switch
Management
/bin/ksh or /bin/
sh
/bin/csh setenv DISPLAY hostname:0.0
DISPLAY=hostname:0.0
export DISPLAY
5. Make sure that the management system has permission to display
windows on hostname. If the management system does not have permission, and if the hostname is using the host-based authorization, use the
xhost command to add the management system to the xhost table on the
hostname system. To do so, on hostname type:
xhost + <managementsystem name>
where managementsystem name is the host name of the management
system. If the hostname is using the MIT-MAGIC-COOKIE-1
authorization, please refer to the xauth man pages to set up the
.Xauthority file.
6. Start the graphical network map (user interface) by typing:
ovw
ovw is executable by anyone.
Alternatively, you can run ovw in the background to free up the ter minal
window for other uses. In some cases, ovw prints error messages to
standard output and stand ar d error. To capture these messages and to

Stopping and Restarting the Manager
Application
Stopping the Manager
Stopping the manager consists of:
1. Exiting the manager’s graphical network map and user interface, and
2. Optionally stopping the manager’s background processes.
To exit from the network map and interfa ce (ovw), select Exit in the map’s
File menu.
Running HP Hub & Switch
If you want the manager to continuously collect data and monitor changes
even when the map and interface are not up (that is, even if you exit from
ovw), do step 1 and not step 2. The background pr ocesses—netmon, trapd,
ovwdb, ovtopmd, and snmpCollect—w ill continue to run and you need only
run /opt/OV/bin/ovw to return to the map and in terface. For more
information on these background processes, refer to the HP OpenView
Network Node Manager Reference manual or read the man page for the
process.
If you want to stop the background processes, use the command /opt/OV/
bin/ovstop. Using ovstop without arguments stops all of the
processes—netmon, trapd, ovwdb, ovtopmd, a nd snmpCollect—in the
correct order.
